I accept that language will change and, in fact, generally welcome the changes which show the language to be alive.
However, I resent and decry the "trendy", "stylish" corruption of the language by TV presenters
This morning I heard a presenter commenting upon Andy Murray's progress and, to finish, she might have said something like "We'll keep you informed of his progress throughout the day".
What she actually said was, "We'll keep you across Murray throughout the day".
Apart from the implied, and somewhat repulsive suggestion of an intimate and enforced contact with Murray , the misuse of the word across appears blatant, deliberate and misleading.
This is not evolution. This is, in my view, corruption.
